1 CTEK D250S DUAL CTEK SmartPass A revolutionary solution for 12V Dual Battery systems
2 It all started simple….One AlternatorOne BatteryOne Starter Motor
3 Then came a fridge, lights, navigation and…. and suddenly the battery was dead.
4 Well, let’s add another battery for all consumers …and a Black Box to separatethe two battery banksDiodesVSRMOSFETRelay

7 But problems remained with: Very long recharge time from alternatorEngine idling just for battery chargingBatteries rarely fully charged, which reduced the useful timeRegular battery replacementSolar panels conflicting with other sources, which reduced outputNo charge of starter battery from solarOverheated service batteriesCostly, difficult to trouble-shoot, expand, modify, ……3-step alternatorSolar panel with dedicated regulatorThick wiresBattery Switch0 – I – II - Both…and a Black Box to separatethe two battery banksDiodesVSRMOSFETRelay110/230V chargerwith multiple outputsBattery watch

11 Let’s start with the basics again One alternator… and a CTEK D250S DUAL that separates the two battery banksConnect the alternator directly to the Starter..add another battery bank
12 Engine off The Starter battery is prepared for engine start …and the Service batteries serve consumers
13 Engine runningCTEK D250S DUAL charges the Service batteries with a temperature compensated charging.High temp => lower voltageLow temp => higher voltage
14 Attach a solar panel directly Synchronized with the alternator when the engine is running
15 The panel serves both batteries when the engine is off …and charging of Service battery with built-in Maximum Power Point Tracker (MPPT)Pulse maintenance of Starter batteryMaximum Power Point
16 LIMITATIONS: 20A max from D250S DUAL Charge current shared with consumers, which prolongs charge time
17 D250S DUAL limitations Max 20A Charge CurrentD250S DUAL charges with 20A until the battery reaches max voltage. The current then tapers off to a fully charged battery
18 D250S DUAL limitations Max 20A Directly from alternator:High current initially (up to 30 minutes)Current tapers off to very low level – 100% charge from alternator almost impossibleCharge CurrentCharge Current
19 D250S DUAL limitations Max 20A Direct charging from alternator could be faster during a short time for:Large alternatorLarge Service Battery bankDeep discharged batteriesCharge CurrentD250S DUAL is faster in the long run, but could be behind during the first minutes.20AmpsCharge Current
20 D250S DUAL limitations Charge current shared with consumers Current used for consumers……prolongs charge time
21 SOLUTION – and more! CTEK SmartPass High charge currents through SmartPass
22 SOLUTION – and more! CTEK SmartPass Low charge current through D250S DUAL.
23 SOLUTION – and more! CTEK SmartPass Green curve => minimized charge time
24 SOLUTION – and more! CTEK SmartPass Almost all current through D250S DUAL is used for charging.Critical consumers directly from batteryChargeConsumeMove non-critical consumers. SmartPass provide current direct from Alternator.
25 Built-in Battery Watch SOLUTION – and more!Built-in Battery WatchConsumeEngine off. Current from the Service Battery
26 Built-in Battery Watch SOLUTION – and more!Built-in Battery WatchService battery and critical items are protected.Engine off. Service battery deep discharged. Disconnect non-critical items.
27 Solar Panel serves all batteries! SOLUTION – and more!Solar Panel serves all batteries!Solar panel charges Service battery and maintains Starter batteryChargeMaintainCharge
28 Overheat protection of Service battery SOLUTION – and more!Overheat protection of Service batteryService battery overheated due to age, oversized alternator, high ambient temperature.Charge60°
29 Overheat protection of Service battery SOLUTION – and more!Overheat protection of Service batterySmartPass disconnects direct path from alternator. D250S Dual finalize charge with reduced voltage and currentCharge55°
30 110/230V charger serve both battery banks with one output SOLUTION – and more!110/230V charger serve both battery banks with one outputChargeChargeChargeAC/DC charger charges both Service and Starter battery
